The U.S. Food and Drug Administration (FDA) has granted approval for the first medication aimed at treating severe frostbite, marking a significant milestone in medical treatment options for this condition.
The newly approved drug, iloprost, sold under the brand name Aurlumyn, is designed to mitigate the risk of amputation of fingers and toes due to severe frostbite. Originally developed for the treatment of pulmonary arterial hypertension, iloprost has now been repurposed to address the specific challenges posed by frostbite.
Significance of Approval
Dr. Norman Stockbridge, Director of the Division of Cardiology and Nephrology at the FDA’s Center for Drug Evaluation and Research, hailed the approval as a groundbreaking development in frostbite treatment. He emphasized the importance of this new option in preventing the devastating consequences of frostbite-related amputations.
Frostbite occurs when exposure to extreme cold causes tissue damage, primarily affecting areas such as the fingers, toes, nose, cheeks, and chin. Initial symptoms may include numbness, tingling, or changes in skin color, progressing to severe manifestations such as white or blue skin and fluid-filled blisters. If left untreated, frostbite can result in permanent tissue damage or the need for surgical amputation.
Mechanism of Action
Iloprost, the active ingredient in Aurlumyn, functions as a vasodilator, meaning it widens blood vessels and prevents clot formation. This mechanism of action is crucial in severe frostbite cases where both the skin and underlying tissue are affected, leading to compromised blood flow.
The FDA’s approval of Aurlumyn follows a rigorous clinical trial involving 47 adults with severe frostbite. Participants were divided into three groups, with one group receiving iloprost intravenously for six hours daily for up to eight days. The second group received iloprost in combination with other medications not approved for frostbite, while the third group received alternative medications without iloprost.

Promising Outcomes
The results of the clinical trial were promising, with participants who received iloprost demonstrating a significantly lower need for amputation compared to those in the other groups. Notably, none of the patients treated with iloprost alone required amputation, highlighting the drug’s efficacy in preserving blood flow and preventing tissue damage.
Dr. Marc Siegel, a clinical professor of medicine at NYU Langone Medical Center, emphasized the importance of this approval in preventing the complications associated with severe frostbite. He praised iloprost as a vasodilator that preserves blood flow and prevents the need for amputation, based on the trial’s findings.
Developer and Side Effects
Aurlumyn was developed by Eicos Sciences Inc. in Maryland. While the drug has shown efficacy in preventing amputation, the FDA noted that it may cause some side effects, underscoring the importance of careful monitoring and patient management during treatment.
The FDA’s approval of Aurlumyn represents a significant advancement in the treatment of severe frostbite, offering hope to patients at risk of amputation due to this debilitating condition. As medical science continues to evolve, innovative treatments like iloprost pave the way for improved outcomes and enhanced quality of life for individuals affected by frostbite.
